A fluorine-containing compound exhibiting excellent surface tension-reducing ability despite the absence of perfluoroalkyl group having a chain length of 8 or more which had been the cause of the PFOS and PFOA problems and use of a fluorine material with low environmental load is provided. Also provided are a fluorine-containing surfactant and a composition thereof, an aqueous resin emulsion and a floor polish composition containing such surfactant. The fluorine-containing compound is represented by the following formula (1) : Rf 1 -C p H 2p -CH(OH)-C q H 2q -NR-C r H 2r -(O) n -SO 3 M (1) wherein Rf 1 is a C 1-6 perfluoroalkyl group, p, q, and r are independently an integer of 1 to 6, M is a cationic atom or atomic group, n is 0 or 1, R is hydrogen atom, a C 1-12 alkyl group, or a group represented by the following formula (2):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒRf 2 -C s H 2s -CH(OH)-C t H 2t -€ƒ€ƒ€ƒ€ƒ€ƒ(2)
wherein Rf 2 is a C 1-6 perfluoroalkyl group, and s and t are independently an integer of 1 to 6. |
